TIME, SPEED, ANDDISTAINCE REooRDER.

SPECIFICATION forming part of Letters Patent N 0. 734,156, dated July 21, 1903.

Application filed April 5, 1902. Serial No. 101,569. (No model.)

T (0% whom it may concern.-

Be it known that 1, RICHARD FITZ GERALD BAXANDALL,a subject of the King of England, residing at ()regneish, Ben Rhydding, in the county of York, England, have invented certain new and useful Improvements in Time, Speed, and Distance Run and Gradient Indicators and Recorders for Motor-Vehicles and other Vehicles, of which the following is a specification.

This invention relates to a new or improved apparatus for use with motor-cars and other vehicles for indicating and recording on one diagram the time the vehicle is in motion, the speed of running and the distance run, and the gradient or contour of the road or path traversed.

To fully describe my invention, reference is made to the accompanying sheets of drawings, forming a part of this specification, in which similar reference numerals indicate corresponding parts in each of the views.

. Figure 1 is a front view of my improved apparatus. Fig. 2 is a sectional plan. Fig. 3 is a cross-section on the broken line a b, Fig. 1. Fig. 4 is a sectional elevation looking from behind. Fig. 5 is a cross-section showing the gradient-recording device. Figs. 6 to 10 are views illustrating the clock. Figs. 11 and 12 are views of detail hereinafter referred to. Fig. 13 is a view, on a larger scale, of part of Fig. 1. Fig. 14 is a cross-section of the case, showing a left-hand side view of Fig. 13.

The case 2 is fitted with a glass front 3 and a milometer or mile-indicating device 4, consisting of any suitable counting train of wheels adapted to'bring (when operated in the manner hereinafter described) the requisite figures on the disks 6 in front of the opening 7 in the face 8 to indicate the distance in miles the vehicle has'run. A similar arrangement is provided above, but modified to the extent required to indicate at the opening 10 the number of hours and minutes the vehicle has been running.

The recording device consists of a band or ribbon of paper 12, carried on a storage cylinder or reel 13 and wound therefrom onto the recording-drum 14. Y A portion of a diagram is shown in Fig. 11. Metallic paper is preferably used-that is to say, paper capable of being marked by a metallic pencil or point.

This paper is automatically ruled with a number of parallel horizontal lines 15 by a number of metallic pencils or points 16, arranged to bear upon the paper upon the recordingdrum 14. The points 16 are carried by the spring-fingers 17 on the curved arm 18, fixed on the spindle 19, mounted in bearings 20in the brackets 21, supported on the side frame 22 of the counting devices. A spring 23 under tension is arranged to draw the arm 18 in the direction required to keep the points 16 bearing upon the paper, andthe springy nature of the fingers l7 counteracts any want of un formity in the length of the pencils or points. Fig. 12 is an elevation of the arm 18 with part in the middle broken away.

A cam or projection 25 on thefirstindicating disk or wheel 26 of the distance-indicating device 4 is arranged to engage the incline 27 on the lever 28 and lift such lever at each revolution. stud 29, and its other end projects beneath the pin 30, fixed in the spindle 19, so that each time the lever 28 is actuated by the cam 25 the spindleilt) is lifted and the pencils 16 make a vertical line 31 on the recording-paper 12. The spring 32 at the top of the spindle presses the latter down again to its normal position as soon as the cam 25has passed the incline 27. The cam or projection 33 on the driving-spindle 34 of the time-recording device 36 is provided to lift the lever 37, pivoted upon the stud 38, at each revolution. The other end of the lever 37 projects heneath the pin 39, fixed in the spindle 19, so that each time the lever 37 is lifted the spindle is raised as Well; but the movement of this lever is limited by the size of the cam and the points of operation to such an extent that the vertioal lines ruled by the points 16 do not join each other, and the joint result is-a series of short lines forming the broken line 31, as shown in Fig. 11, which represents a portion of the paper 12 with the recording lines thereon. The lever may be actuated every fifteen minutes or at the expiration of any other desired periods of time. The unbroken lines distinguish the lines ruled to record the mileage from the time-recording lines, (the broken lines.) It is, however, immaterial which is used for the one or the other.

The lever 28 is pivoted on the ICC The gradient-indicating finger 40 is car ried by the arm 41, and the recording-pencil 42 is fixed at the end of the curved branch 43 of the arm 41. Vv'hen the vehicle is on a horizontal path, the arm 41 lies in the position shown in Figs. 1 and 5, and as the path departs from the horizontal the end carrying the finger 40 is raised either up or down the scale 44 by the connection with the pendent lever 45, pivoted upon the stud 46 and having a weight 47 heavy enough to keepit vertical. A sector 48 is provided on the lever in gear with the intermediate wheel 49, mounted on the stud 50, and this wheel engages the wheel 51 on the stud 52. The wheel 51 carries the crank-arm 53, to which the end of the arm 41 is pivoted, and such arm is supported by the bridle-rod 54, hanging from the stud 55. The crank 53 is of such a length that the arc it describes in its movement converts the are that would otherwise be described by the pencil 42 as the gradient varies into a practically straight line up or down and enables the pencil as the paper moves to mark the line on the paper. The scale 44 is preferably inclined inward from the center to the top and the bottom, as shown in Fig. 5, as the length of the arm causes the finger 40 to move in a curved path.

The speed-indicating apparatus consists of a device for showing the maximum speed attained during consecutive periods of time say, for instance, every thirty seconds. For this purpose I employ a sector 65, pivoted upon the stud 66 and connected to the coiled spring 67, adapted to draw it around until the projection 68 thereon engages the stop 69 each time it is free to move and does not occupy such a position. The sector also carries a projection 70, which as the sector moves to its definite position engages a lever 71, pivoted on the shaft 72, and as the movement is completed presses the end of such lever beneath a detent 73, pivoted on the fixed stud 74. The detent is provided with an arm 75, which is engaged by the periodically-operated cam 76 at each revolution of the latter for the purpose of releasing the detent. The arm 78 of the lever 71 carries a wheel 79, driven by the wheel 80,fixed on the shaft 72,which shaft is constantly driven when the vehicle is in motion by a connection with the driving-shaft or anyother part revolving at a definite speed in relation to the speed of the vehicle. This movement of the lever 71 brings the wheel 79 into gear with the sector, and the latter is thereby turned on its pivot at a speed directly in ratio to the speed at which the vehicle is running. A ratchet-wheel 84, concentric with the sector 65, is provided, and it is turned with the sector 65 by the pin or projection 85 on its face being engaged by the pin or projection 86 on the face of the sector. As soon,

however, as: the cam 76 releases the detent 73 the lever 71, under the influence of the spring 88,moves sufficiently to disengage the wheel 79 from the sector, which under the influence of the spring 90 immediately turns back to its definite position, leaving the ratchet-wheel, which is retained by its pawl 89, in the position the sector moves it to. Immediately before the projection 68 engages the stop 69 the projection 70 engages the lever 71 and moving the latter on the shaft 72 again brings the wheel 79 into gear with the sector 65. If this distance is-greater, the ratchet-wheel is carried still farther around, but if less the projection on the sector does not reach the point it previously did, and as the cam 76 is arranged to disengage the pawl 89 from its ratchet-wheel 84 previously to disengaging the detent 73 and the ratchet-wheel is free to move back under the influence of its spring 90 until the projection 85 on the ratchetwheel 84 meets the projection 86 on the sector. The spring 90 is secured by one end 90 to the ratchet-wheel 84 and by the other end to the hub 91. The hub 91 of the ratchet-wheel passes through the sector and has the spurwheel 92 fixed on its end. The movement of the wheel 92 is communicated by the wheel 93 on the stud 94 to the wheel 95, the spindle 96 of which carries the pointer 97, which indicates on the scale 98 the rate of miles per hour that the vehicle is then running.

For the purpose of recording the different rates of speed upon the paper 12 a recordingpoint 100 is provided on the spring-arm 101, secured to the wheel 102, mounted on the stud 103, fixed in the face of the ratchet-wheel 84. The wheel 102 is half the diameter of the semicircular stationary sector 104, fixed concentric with the ratchet-wheel and having internal teeth engaging the teeth of the wheel 102. The point 100 is located on the pitchline of the teeth of the wheel 102 and in such a position that when the wheel 102 is engaging the center of the sector the recordingpoint is diametrically opposite such center. Therefore the point moves in a vertical line when the wheel is rotated and marks the line 109 upon the paper 12.

The recording-drum is preferably driven by the worm on the shaft 121, driven by the wheels 122 and 123 from the shaft 72, driven by its worm-wheel 125, actuated by its worm 126 on the shaft 127, driven from the driving-shaft of the vehicle in any convenient way. The shaft 127 is divided and one part is driven by the ratchet-wheel 124, engaged by the paw1128, carried by the other part, so that when the vehicle is moving backward the part carrying the worm 126 is not actuated.

The cam-shaft 129 of the cam 76 is driven by the clock 130, located, by preference,within the drum 14. The speed of the clock is shown to be regulated by the flier 131; but any other device may be used. It is driven by the spring 132, which may be automatically wound. The shaft 129 carries a spur-wheel operated by the wheel 140, intermittently driven by the wheel 142, engaged at each revolution of the wheel 143 by its tooth 14 i and moved one tooth. The wheel 143 is driven from the clock in any convenient way. The clocli'(separately shown in Figs. 6 to 10) is automatically wound from the shaft 121, connected by the train of wheels to the shaft 151, on which the Wheel 152 is fixed. This wheel is connected to the wheel 154 by the intermediate wheels 155 and constantly drives it while the vehicle is in motion, and the ratchet-wheel 156 is fixed to the wheel 154. A pawl 157 connects the wheel 156 to the ratchet-wheel 158, and one end of the spring 132 is connected to 158, while the other end is connected to the main driving vheel 160 of the clock. It the ratchet-wheel is moving faster than it is necessary to keep the clock wound up, the stud 162 on the end 163 of the pawl meets the projection 164 on the wheel160 and throws the pawl out of gear with the ratchet 156. The pawl 165 engages the ratchet-Wheel158 and prevents it slipping back. Figs. 9 and 10 represent parts of the mechanism on a larger scale. 4

The mile-counter 4 is driven from the shaft 72 by the bevel-wheels 170, the shaft 171,and the wheels 172. The ti me-indicator is driven by the ratchet-wheel 180, operated by the pawl 181 on the end of the sliding piece 182, reciprocated by the arm 183 of the rocking lever 71. The spring-pawl 185 is provided to prevent the ratchet-wheel moving backward.

The distances between the points 16 increase toward the center, so as to draw the lines 15 wider apart,according to their distance from the edge of the paper, and thus compensate in the diagram 109 the diminishing movement of the pencil 100 as it moves away from the center. 7

I claim- 1. In a device of the character described the combination with a moving band,of a plurality of pencils bearing thereon and adapted to mark longitudinal parallel lines on the band, and means for simultaneously moving all said pencils transversely of the band to mark transverse lines intersecting the longi tudinal lines, substantially as described.

2. In a device of the character described the combination with a moving record-band of a pivoted member having a plurality of spring-fingers, markingpencils carried by said fingers and bearing on the paper, and

means for periodically moving said pivoted member at right angles to the line of travel of the band a distance equal to the space between the pencils, and returning it to initial position, substantially as described.

3. In adevice of the character described, the combination with the moving record strip or band, of a movable member, a plurality of equally-spaced pencils carried thereby, adapted to rule a plurality of equally-spaced longitudinal lines on said band, and means for simultaneously moving said movable member transversely of the band at suitable intervals a distance equal to the space between two longitudinal lines whereby parallel transverse lines are formed extending clear across the band and intersecting the longitudinal lines, substantially as described.

4. In combination,the sector 65,the ratchet- Wheel 84, means for driving the sector from the motion of the "ehicle and means for pcriodically throwing such driving mechanism out of gear all arranged and operating substantially as herein shown and described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
